How to retrieve Javascript function value in webview component
android, android-webview, dom-events, javascript
Solution
You can't, directly.
You can call the Javascript function via `loadUrl("javascript:...")`, where `...` is your function call. However, you cannot get a result this way.
If you inject a Java object into the Web page via `addJavascriptInterface()`, you could set up another function that called the function you want and returns that value via a call to the injected Java object. That only works if you can modify the Web page, though.
Problem
How can I retrieve the Javascript function value from a web page loaded withing a webview component??
